The U.S. -based social sharing platform company this morning announced that it has raised a whopping $20 million in a Series D round of funding led by Institutional Venture Partners, with existing backers such as NEA and Novak Biddle Venture Partners participating.

They aggregated news thought user submission, allowed people to vote articles up or down and built large communities of engagement. XYDO is not that much different but adds the layer of the social graph, making its user base much wider. Podio Is Like A Yammer With Its Own App Store And App Builder.

Look out Yammer – Podio emerges with full business social network. When Danish entrepreneur Tommy Ahlers sold his ‘social phonebook’ ZYB to Vodafone in 2008 for €31 million and joined the company, it didn’t seem like he would stay forever at such a slow-moving corporate entity.

Meebo. To most people, online chat service Meebo is best known for its multiprotocol webchat, but for over a year now its primary focus has been the Meebo Bar — a persistent toolbar that third party websites can embed on their pages to facilitate sharing through services like Facebook, Twitter, and email. That bar now reaches nearly 150 million people per month through dozens of large third party integrations. Last week CEO Seth Sternberg swung by TechCrunch headquarters to discuss the current status of the Bar, and how it’s turning a single ad unit into some serious revenue. We last did a deep dive on the progress of the Meebo Bar in December, when Quantcast figures showed it reaching nearly 100 million unique visitors across Meebo partner sites.
